What this calculator estimates
Size a loan using DSCR, LTV and debt-yield constraints. It combines the inputs below to produce Maximum supportable loan. Every assumption remains editable so the estimate can reflect the property, financing and location being evaluated.
Worked example
Using the displayed sample assumptions, the calculator produces $3,500,000. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.
Inputs and assumptions
- Property value — sample input: 5000000 currency units
- Annual net operating income — sample input: 350000 currency units
- Minimum DSCR — sample input: 1.25 times
- Maximum LTV — sample input: 70 %
- Minimum debt yield — sample input: 8 %
- Interest rate — sample input: 6 %
- Amortization — sample input: 25 years
How to interpret the result
Run downside, expected and upside cases before relying on the output. Compare a conservative case with an expected case and keep a record of the assumptions used.
Common mistake to avoid
Do not assume exit value, financing and income forecasts are certain. Local definitions, taxes, lending practices and measurement requirements can materially change the result.
